基于混杂自动机的电容器充电电源建模方法

Modeling method of capacitor charging power supply based on hybrid automata

针对串联谐振电容器充电电源具有高阶、多模态、强非线性的特点,提出了一种基于混杂自动机的建模方法,该方法通过描述系统的连续时间变量和离散状态变量之间的关系来展现系统的混杂特性。基于该方法建立了系统的混杂自动机模型,并提出了一种基于上述模型的分段线性充电控制策略,通过搭建仿真模型验证了该模型和控制策略的有效性。

To describe the operation mechanism of series resonant capacitor charging power supply（SR-CCPS） which is a high-order, multi-operating-mode nonlinear system visually, a hybrid automata model is built in this paper utilizing hybrid system theory. Based on the model, a piecewise linear（P-L） charging control method is proposed to realize multi-speed charging for S-R CCPS. The simulation results have verified the validation of the proposed model and method.
